For service in wars before statehood, refer to Massachusetts—Military Records. However, a few printed sources have attempted to extract Maine soldiers from the Massachusetts holdings, notably Charles J. House, Names of Soldiers of the American Revolution who Applied for State Bounty...in Land Office (1893; reprint, Baltimore: Genealogical Publishing Co., 1967); Charles A. Flagg, An Alphabetical Index of Revolutionary Pensioners Living in Maine (1920; reprint, Baltimore: Genealogical Publishing Co., 1967); and Carleton and Sue Fisher, Soldiers, Sailors and Patriots of the Revolutionary War—Maine (Louisville: National Society of Sons of the American Revolution, 1982).

The adjutant general’s holdings for Maine, which include militia on state service in wars, published yearly reports on Civil War soldiers. World War I and II reports are held at Maine State Archives. The Spanish-American War service records are also held at the state archives but are not published.

Maine State Archives has a card index of each Civil War soldier and grave records for Revolutionary, Civil War, and War of 1812 soldiers, as well as service records through World War I. In addition, there are listings of veterans by town of those who served in World War II, Korea, and Vietnam.

At Ancestry.com, subscribers can access Maine Military Men, 1917-1918 which provides the names of men who served in the army, navy, and marines during World War I and also includes a list of nurses.
